UCY2E271MHD6

The UCY2E271MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UCY series. It is a radial‑lead, polarized can designed for high ripple current and long life operation, rated 270 µF at 250 V with a temperature range of −40°C to +105°C.

Engineered for demanding power applications, this capacitor suits power supply filtering, ballast circuits and electronics requiring durable performance under elevated temperature and ripple load. AEC‑Q200 qualification and RoHS compliance support use in regulated, reliability‑focused designs.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 250 V rated voltage, with a tolerance of −20% to +20%.
• High Ripple Current Handling — Low‑frequency ripple current 1.35 A (120 Hz) and high‑frequency ripple current 2.7 A (100 kHz), enabling robust smoothing under dynamic loads.
• Long Life Endurance — Rated for 12,000 hours at +105°C under DC bias plus rated ripple current, supporting extended service life in high‑temperature environments.
• Temperature Range — Operates from −40°C to +105°C for broad environmental tolerance.
• Low Loss (tan δ) — Loss tangent (tan δ) specified at 0.20 (measured at 20°C, 120 Hz), supporting stable performance in AC and ripple conditions.
• Compact Radial Package — φ16 × 40 mm can with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assemblies and hand or wave soldering processes.
• AEC‑Q200 Qualified & RoHS Compliant — Meets AEC‑Q200 qualification and RoHS directive requirements for regulated markets and higher reliability applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support production and prototyping workflows.

Typical Applications

• Power Supplies — Bulk smoothing and output filtering where high ripple current and 250 V rating are required to stabilize DC rails.
• Ballasts and Lighting Electronics — Energy‑handling and ripple suppression in ballast circuits as indicated by the UCY series datasheet guidance.
• Automotive Electronic Modules — Suitable for automotive electronics and control modules where AEC‑Q200 qualification and wide temperature operation are required.
• Industrial Power Electronics — Filtering and decoupling in industrial converters and drivers that demand long life at elevated temperatures.

Unique Advantages

• High Ripple Capability: Rated ripple currents of 1.35 A (120 Hz) and 2.7 A (100 kHz) reduce heating and extend life under AC stress.
• Extended High‑Temperature Life: 12,000 hours endurance at +105°C provides predictable longevity in hot operating conditions.
• Automotive‑Qualified: AEC‑Q200 qualification supports use in regulated automotive and high‑reliability environments.
• Compact Radial Form Factor: φ16 × 40 mm can and 7.5 mm lead spacing offer a space‑efficient through‑hole solution for power boards.
• Stable Loss Characteristics: Specified tan δ = 0.20 at 20°C/120 Hz for consistent AC behavior and predictable design margins.
• Regulatory Compliance: RoHS compliant to meet environmental and supply‑chain requirements.
